Chip electronic components and mounting structure for the same

A chip electronic component comprising:

• a body of the chip electronic component having outer peripheral surfaces including an upper surface, a lower surface and a pair of side surfaces;
• an electronic component element having electrodes and defining part of said body of the chip electronic component;
• and
• a plurality of external electrodes arranged so as to extend over at least the lower surface and at least one of the side surfaces of said body of the chip electronic component and electrically connected to the electrodes of the electronic component element;
• wherein each portion of said external electrodes provided on the lower surface of said body of the chip electronic component is arranged to have an almost uniform width from one longitudinal end to the other, and satisfy the relation L1<L3, where L3 is the width of each portion of the external electrodes provided on the lower surface of said body of the chip electronic component, and L1 is the width of each portion of the external electrodes provided on the at least one side surface of said body of the chip electronic component, each of the widths L1 and L3 being defined as a dimension of the external electrodes measured in a longitudinal direction of the body of the chip electronic component.
